From an AP release, the story seems pretty slanted (bolding mine)

Belmar said at a news conference Sunday morning that a Ferguson Police officer had an encounter with two people. He says one person allegedly pushed the officer back into patrol car and assaulted the officer.

He says there was a struggle over the officers’ weapon and one shot was fired in the car. The officer then got out of his vehicle and shot at “a subject.”

He says the man suffered more than a couple gunshots, but “not many more than that.”
